Specification of Letters Patent.

Patented March 2, 1909.

Application filed June 29, 1908. Serial No. 440,862.

To all whom it may concern:

Be it known that I, ABRAHAM SIMONS, a subject of the Czar of Russia,resioing at Schenectady, county of Schenectady, and State of New York,have invented certain new and useful Improvements in Flush Meters, ofwhich the following is a saccitication.

The invention relates to such improvements and consists of the novelconstruction and combination of parts hereinafter described andsubsequently claimed.

Reference may be had to the accompanying drawings, and the referencecharacters marked thereon, which form a cart of this specification.

Similar characters refer to similar parts in the several figurestherein.

This invention is especially adapted for use in flushing closet-bowls.

The principal objects of the invention are to provide means for flushingthe bowl during a predetermined interval of time and for regulating theduration of such interval as may be desired.

The invention consists of a case-valve having ingress and egressopenings, a main passageway and a pressure-regulating passagewayconnecting such openings, a differential valve movable along a part ofthe regulating passageway but controlling the main passageway, a valvefor controlling the regulating passageway, means for operating thepressure-regulating valve, whereby the actuating pressure upon thedifferential valve is controlled, and means for limiting the extent ofmovement of the ditferential valve, whereby the duration of the flushingoperation can be varied as desired.

Figure 1 is a view in side elevation of the improved meter. Fig. 2 is avertical longitudinal central section of the same showing the flushingvalve closed. Fig. 3 is a simi lar section showing the valve opened.Fig.

1 is a top plan-view of the meter as shown in Fig. 1. Fig. 5 is a topplan view of the valve-stop detached. Fig. 6 is an edge view of thesame. Fig. 7 is a bottom plan view of the differential valve detached. Fig. S is a side elevation of the same. Fig. 9 is a top plan view of thevalve-scat block detached. Fig. 10 1s a side elevation of the same.

The meter comprises a containing case, 1, l havin an IIIOIQSS o enm 2and an e ress 2:, p: 7 as opening, 3, which openlngs are separated! bythe diaphragm *1: preferably cast integral with the case. A valveseat-block, 6, shown detached in Figs. 9 and 10, is inserted in anaperture in the diaphragm adapted to receive and closely fit the same,as seen in Figs. 2 and The seat-block is provided withoppositely-disposed annular grooves, 7, one on its upper side and one onits lower side, which grooves are connected by a series of apertures, 8,extending through the seatblocl: and forming parts of the mainpassageway connecting the ingress and egress openings. This seat-blockis also provided with the central aperture 10, in which is fixed thelower end of a tubular post, 12, which forms a slide-way or guide forthe diii'erential valve, let. This valve consists oi the lower member,15, adapted to close the apertures 8 in the seat-block and the member16, having a greater cross-sectional area than the member 15, andadapted to approximately close and move along the runway, 17. The twomembers 153 and 16 are connected by the tubular body-portion, which isadapted to receive and loosely fit upon the post 12. The tubular postextends upwardly along the center of the run-way 17, and beyond thesame, into chamber 20, formed in the cap 21, which cap is detachablysecured to the upper end of that part 01" the case wall which containsthe run-way, by means of screw-threads, 22, on the cap and case-wall.The upper end of the tubular post is screw-threaded exteriorly toreceive the valve-stop, 24, containing a central screw-threadedaperture, 25, adapted to re ceive and lit the post. The convexperipheral edges, 26, are concentric and adapted to fit the interior ofthat part of the case containing the run-way, and are capable of beingmoved longitudinally of the run-way when the stop is rotated on thepost, thereby varying the length of the run-way. The indentations, 28,form openings which connect the run-way with the cap-chamber. The upperend of the tubular post is provided with a conical valve, 30, providedwith a stem, 31, passing down through and projecting from the lower endof the tubular post.

Vhen this valve is opened, a regulating passageway is formed leadingfrom the ingress opening 2 up the run-way 17 through openings 28, intothe cap-chamber 20, down the passageway in the tubular post to theegress opening 3.

As a means for operating the regulating valve 30, there is provided arock-shaft, 32, rotatory in bearing 3%, having on its outer end anoperating handle, 35, and on its inher end a sleeve, 36, fixed on theshaft and provided with rock-lever, 37, adapted to engage the lower endof the stem 31; also the stops 38 and 39, adapted to engage a caselug,40, for the purpose of limiting the rockmovements of the shaft. Thevalve is shown closed in Fig. 2, and opened in Fig. 3. It is notessential that the regulating passageway should lead to the egressopening In Fig. 2 the main or differential valve and the regulatingvalve are both shown in closed position. The ingress opening 2 beingconnected with a water-supply pipe, the hydrostatic pressure of thewater maintains both valves in closed position. The upper member 16 ofthe main valve being somewhat smaller in cross-sectional area than thecrossectional area of the run-way 17, leaves an open passageway ofcomparatively small capacity between the ingress opening, run-way l7 andthe cap-chamber 20 so that the full hydrostatic pressure of the wateracts upon the regulating valve to maintain the same in a closedposition, and also upon the lower member 15 of the main valve to closethe latter valve, the pressure upon the upper side of the member 16being sutlicient to balance the pressure upon the lower side of suchmember.

The flushing operation of the device is as follows: The crank-handle 35is lifted by the hand of the operator, which positively opens theregulating valve 80, thereby opening the regulating passageway andrelieving the hydrostatic pressure upon the upper side of the uppermember 16 of the main valve, which causes the pressure upon the lowerside of such member to open the main valve and raise it from theposition shown in Fig. 2 to that shown in Fig. 3, the water which was inthe run-way 17 above the main valve passing freely through the apertures28 down the tubular post to the atmosphere, or the egress opening 3. Theoperating crank-ham dle is then released, which allows the regulatingvalve to close by gravity. Immediately upon the closing of such valve,the hydrostatic pressure upon the main valve becomes balanced, whereuponthe main valve slides by gravity down the tubular post and along therun-way 17 to the position which closes the main passageway, shown inFig. 2. The speed at which the diflerent-ial or main valve descendsalong the run-way depends upon the area of the opening'between suchvalve and the case-wall containing the runway,because the water in therun-way beneath the valve, when at its highest position, as shown inFig. 8, must pass the valve while the latter is descending. The timerequired for the valve to descend to its closing position also variesdirectly as the length of the run-way. By lengthening the run-way, thetime of descending is increased, and the time required for the valve todescend is shortened by shortening the run-way. It is obvious that themain passageway continues open while the difierential valve isdescending. The adjustable stop 24 afiords a means for lengthening andshortening the run-way, and thereby regulating the time-length of theflushing-period. By removing the cap 21, the adjustable stop is renderedeasily accessible for changing its adjustment.

hat I claim as new and desire to secure by Letters Patent is In aflush-meter of the class described, the combination with a case havingingress and egress openings, main and regulating passageways, and avertical run-way forming a part of the regulating passageway; of adiaphragm between such openings, containing apertures which form a partof the main passageway; a tubular guide-post erected from suchdiaphragm, extending down through such diaphragm and upwardly along thecentral line of such run-way and beyond the same; a difierential valvecomprising a tubular body adapted to receive and slide upon the tubularpost, having at its lower end a member adapted to close the apertures inthe diaphragm, and upon its upper end a member larger in cross-sectionalarea than the member at the lower end and adapted to approximately closeand move along the run-way to its upper end; a stop at the upper end ofthe run-way for limitin the upward movement of the differential valveand adjustable longitudinally of the tubular guide-post, whereby thelength of the run-way may be varied by changing the adjustment of thestop; a detachable cap secured to the upper end of the case-wallcontaining the run-way, having a closed chamber containing the upper endof the post and counetting with the run way; a gravityclosing valve forclosing the regulating passageway which leads from the inlet opening upthe run-way into the cap-chamber and down the tubular post; avalve-controlling stem extending from the regulating valve down throughthe tubular post, and means extending exteriorly of the case for raisingsuch stem to open such valve.

In testimony whereof, I have hereunto set my hand this 26 day of June,1908.
